數控銅排(pai)加(jia)工(gong)機的(de)精(jing)(jing)(jing)密(mi)(mi)(mi)(mi)化是為了適應高新技術發展的(de)需要(yao)(yao)，也是為了提高普通機電(dian)產品的(de)性能、質(zhi)量和可靠性，減(jian)少其(qi)裝配時(shi)的(de)工(gong)作(zuo)量從而(er)提高裝配效率的(de)需要(yao)(yao)。數控銅排(pai)加(jia)工(gong)機新材料(liao)及(ji)新零件(jian)的(de)出現，更(geng)高精(jing)(jing)(jing)度要(yao)(yao)求的(de)提出等都需要(yao)(yao)超(chao)(chao)精(jing)(jing)(jing)密(mi)(mi)(mi)(mi)加(jia)工(gong)工(gong)藝，發展新型超(chao)(chao)精(jing)(jing)(jing)密(mi)(mi)(mi)(mi)銅排(pai)加(jia)工(gong)機，完善現代(dai)超(chao)(chao)精(jing)(jing)(jing)密(mi)(mi)(mi)(mi)加(jia)工(gong)技術，以適應現代(dai)科技的(de)發展，超(chao)(chao)精(jing)(jing)(jing)密(mi)(mi)(mi)(mi)加(jia)工(gong)主要(yao)(yao)包括超(chao)(chao)精(jing)(jing)(jing)密(mi)(mi)(mi)(mi)切削、超(chao)(chao)精(jing)(jing)(jing)密(mi)(mi)(mi)(mi)磨削、超(chao)(chao)精(jing)(jing)(jing)密(mi)(mi)(mi)(mi)研磨拋光以及(ji)超(chao)(chao)精(jing)(jing)(jing)密(mi)(mi)(mi)(mi)特種加(jia)工(gong)。

隨著現代科(ke)學技術的(de)發展，對超精密(mi)加(jia)工技術不斷提出(chu)了新(xin)的(de)要(yao)求。從(cong)精密(mi)加(jia)工發展到(dao)超精密(mi)加(jia)工，是世界各工業(ye)強國致力發展的(de)方向。數控銅排加(jia)工機(ji)精度(du)從(cong)微米(mi)級(ji)到(dao)亞微米(mi)級(ji)，乃(nai)至納(na)米(mi)級(ji)，其應用(yong)(yong)范圍日趨廣泛。母線處于高電(dian)(dian)位，目(mu)前國內專門用(yong)(yong)于高壓(ya)母線及電(dian)(dian)接觸(chu)發熱測量(liang)的(de)儀器還很少。溫(wen)度(du)監測的(de)主要(yao)方法一(yi)是在電(dian)(dian)接觸(chu)表面(mian)涂一(yi)層隨溫(wen)度(du)變化(hua)顏(yan)色(se)的(de)發光材料，通(tong)過觀察其顏(yan)色(se)變化(hua)來大致確(que)(que)定溫(wen)度(du)范圍，這(zhe)種方法準(zhun)確(que)(que)度(du)低(di)、可靠(kao)性差(cha)，不能進(jin)行定量(liang)測量(liang)；根據(ju)高電(dian)(dian)壓(ya)作業(ye)環境下(xia)溫(wen)度(du)測量(liang)的(de)特點，數控銅排加(jia)工機(ji)母線和(he)電(dian)(dian)接觸(chu)溫(wen)度(du)測量(liang)裝置(zhi)采取溫(wen)度(du)就地測量(liang)，數據(ju)遙送地面(mian)，由計(ji)算機(ji)進(jin)行處理的(de)方法。

溫(wen)(wen)度傳(chuan)感(gan)器由浮動(dong)(dong)充電(dian)電(dian)池供電(dian)，減少高(gao)低壓之間的(de)(de)電(dian)氣聯系，采用全數字方式工(gong)(gong)(gong)作(zuo)，抗干(gan)(gan)擾能力(li)強、精(jing)度高(gao)、體(ti)積小。經系統綜(zong)合測(ce)試，其工(gong)(gong)(gong)作(zuo)穩(wen)定(ding)(ding)可(ke)靠(kao)，能夠滿足高(gao)壓母(mu)線(xian)(xian)溫(wen)(wen)度測(ce)量(liang)的(de)(de)要求。在高(gao)壓母(mu)線(xian)(xian)溫(wen)(wen)度測(ce)量(liang)裝(zhuang)(zhuang)置(zhi)(zhi)中，溫(wen)(wen)度傳(chuan)感(gan)部(bu)(bu)分與數據(ju)處理部(bu)(bu)分是(shi)分開的(de)(de)。溫(wen)(wen)度數據(ju)可(ke)通(tong)過(guo)(guo)(guo)(guo)紅外光波或無線(xian)(xian)電(dian)波傳(chuan)給(gei)處于低電(dian)位(wei)的(de)(de)測(ce)量(liang)儀器。由于測(ce)量(liang)點可(ke)能有若干(gan)(gan)個，為便于控(kong)制，測(ce)量(liang)的(de)(de)數據(ju)帶有地(di)址識別(bie)碼。紅外線(xian)(xian)數據(ju)傳(chuan)送的(de)(de)缺點是(shi)光波傳(chuan)輸要求空間無障礙物，傳(chuan)送距離較(jiao)短，一般只(zhi)有3m~5m。夾(jia)(jia)(jia)(jia)緊(jin)(jin)是(shi)工(gong)(gong)(gong)件(jian)裝(zhuang)(zhuang)夾(jia)(jia)(jia)(jia)過(guo)(guo)(guo)(guo)程中的(de)(de)重要組成(cheng)部(bu)(bu)分。不會由于切削力(li)、工(gong)(gong)(gong)件(jian)重力(li)、數控(kong)車床離心力(li)或慣性力(li)等的(de)(de)作(zuo)用而產生位(wei)置(zhi)(zhi)變化和振(zhen)動(dong)(dong)，以(yi)保(bao)證(zheng)加(jia)工(gong)(gong)(gong)精(jing)度和安全操作(zuo)。工(gong)(gong)(gong)件(jian)定(ding)(ding)位(wei)后(hou)必(bi)須通(tong)過(guo)(guo)(guo)(guo)一定(ding)(ding)的(de)(de)機構(gou)產生夾(jia)(jia)(jia)(jia)緊(jin)(jin)力(li)，把工(gong)(gong)(gong)件(jian)壓緊(jin)(jin)在定(ding)(ding)位(wei)元(yuan)件(jian)上，使其保(bao)持準(zhun)確的(de)(de)定(ding)(ding)位(wei)位(wei)置(zhi)(zhi)，這種產生夾(jia)(jia)(jia)(jia)緊(jin)(jin)力(li)的(de)(de)機構(gou)稱為夾(jia)(jia)(jia)(jia)緊(jin)(jin)裝(zhuang)(zhuang)置(zhi)(zhi)。銅排加(jia)工(gong)(gong)(gong)機夾(jia)(jia)(jia)(jia)緊(jin)(jin)裝(zhuang)(zhuang)置(zhi)(zhi)夾(jia)(jia)(jia)(jia)緊(jin)(jin)過(guo)(guo)(guo)(guo)程可(ke)靠(kao)，不改(gai)變工(gong)(gong)(gong)件(jian)定(ding)(ding)位(wei)后(hou)所占據(ju)的(de)(de)正確位(wei)置(zhi)(zhi)。結(jie)構(gou)性好，夾(jia)(jia)(jia)(jia)緊(jin)(jin)裝(zhuang)(zhuang)置(zhi)(zhi)的(de)(de)結(jie)構(gou)力(li)求簡單、緊(jin)(jin)湊，便于制造和維修。夾(jia)(jia)(jia)(jia)緊(jin)(jin)力(li)的(de)(de)大(da)小要適當，既要保(bao)證(zheng)工(gong)(gong)(gong)件(jian)在加(jia)工(gong)(gong)(gong)過(guo)(guo)(guo)(guo)程中其位(wei)置(zhi)(zhi)穩(wen)定(ding)(ding)不變、振(zhen)動(dong)(dong)小，又要使工(gong)(gong)(gong)件(jian)不會產生過(guo)(guo)(guo)(guo)大(da)的(de)(de)夾(jia)(jia)(jia)(jia)緊(jin)(jin)變形。
